FEATURES
±4.5% LED current accuracy Wide input voltage ranges from 7V to 40V 60V breakdown voltage Thermal protection: Current ramp down at 125oC RoHS Compliant and Halogen Free Ultra small form factor Confidential RoHSCompliantandHalogenFree GENERAL DESCRIPTION
Several fixed output current versions provide a simple way to drive LEDs. A maximum voltage rating of up to 60V makes the PS4502 suitable for most DC supply voltage LED lighting applications. And, it will not be damaged by high temperature with the features of a current ramp-down function from junction temperature 125oC to 145oC. There are two ways to integrate PS4502 into an LED driving circuit. One is flip chip type and other is traditional wire bonding technology. Whether using the flip chip or wire bonding method, the PS4502 ensures excellent temperature stability and accurate current control, enhancing the overall efficiency and durability of LED products.
